Application. filed December' 8, 1925, Serial No.

This invention relates to a belt clamp more particularly for adjustablebelts which are subjected to heavy load. For example telegraph operatorsuse adjustable lelts by means ot which the body ot the operator, who isstanding on a stay iron hooked to a telegraph post7 is strapped to thepost. Hitherto such belts wiere secured by the usual prong buckle ofwhich the prong engaged with one of a number oi holes in the belt. Insuch an arrangement the prong is liable to tear through the beltlaterally so that the operator will fall. The same danger is liable tooccur it' it is necessary to adjust the belt when in use as it isnecessary to release it tor this purpose.

When using a belt clamp according to the present invention it is notnecessary to provide the belt with holes and to open it for adjustment;the full strength of the belt is therefore always available. The adjustment is effected in a simple manner by a hand movement even with thestrongest belts and the strength of the closure corresponds with thenecessary requirements at any timeL The new belt clamp consistssubstantially of two loose rings which are connected to the belt in themanner hereinafter described.

The clamp according to the invention is shown in the accompanyingdrawings wherein Figure l. shows a perspective view of a complete belt,and

l*1 igures 2, 3 and Il: show various forms oi rings.

(lne end a of the belt is rigidly secured to a ring c by sewing orriveting. The belt is then passed over a bar or through a ring or eye orthe like (Z and then passes out 'from the bottom into the ring c when itis passed through a second ring e, bearing `from the top against thering e, but without being able to be drawn through the ning e, and thenpasses out oit the ring c on the same side as that on which it waspassed in.

Vililhen the belt is to be used for strapping a telegraph operator to apost the free end of the belt is returned to the eye d, and securedthereto by a strong spring hook. The connecting eye is preferably suchthat the plane olf the spring hook is at right angles to the plane ofthe belt. t

rlhe rings c and e are in this ease forged troni bar iron 8 to l0 mm. indiameter. They may either' be circular like the rings c and a, in Figure2, or they may be liatneil on one T side like the rings c2 and e, inOurc 3, or the outer ring may be provided with oppositely disposedoutward projections as ioure el whilst the inner ring may be ofhorse-shoe shape as shown at e3 in Figure 4 or ot circular shape shownat e4 in Figure 4. rEhe belt clamp may also be used for other purposessuch as for the tightening belts of climbing irons or for snow-shoeattachments and the li re.

(l Claim:`

l. lelt clamp wherein a belt secured at one end to a ring (c) is passedaround a bar or a ring (d) and then back into the first mentioned ring(c), and then passed through a second ring (e) and passed out oi thefirst mentioned. ring (c) on the same opening side as it is passed intothis, but at a peint sitauted diainetrieally opposite to its entrancepoint, substantially as described.

2. Safety 'the belt belt having a clamp wherein secured at one end to aring (c) is passed around a bar or a ring (d) and then back into thefirst mentioned ring (c), then passed through a second ring (c), passedout oi the first mentioned ring (c) on the same opening side as it ispassed into this, but at a point situated diametrically opposite to itsentrance point, and ultiniatel returned to the bar or ring (d) anddetachably connected therewith.
